To all whom il may concern-:- l

lle it known that l, JAMES SHo'rivnLr n citizen ot' thc United States,residing :it lVutsonville. in the county of Santa Cruz und' Stute ol'California, have invented certain new und useful Improvements in SwivelHose-(,loilplings. ot' which the following is a spcciticution, referencebeing` had to the accompanying1 drawings.

This invention relates to improvements in detachable couplings for hose,pipes und similar conductors.

The object. of tho invention is to provide a. practical detachableswivel coupling of this character which ivill provide un eli'ectivejoint for the sections of waiter, nir and other fluid conductors. v

`With the above :ind other objects in view, the invention consists ofthe novel features of construction :1nd the combination and nr,-ranwement, of parts hereinafter fully described and claimed, andillustrated in the accompanying drawings, in which- Figure 1 is a sideVelevation of my improvedcoupling; Fig. 2 is a. longitudinal section;Fig. 3 is u cross section token on the line 3--3 in Fig. 2; Fig. 'i is alongitudinal section through the sleeve section of one 'member of thecoupling; and Fig. 5 is a side elevation of the other member of thecoupling.`

VThe invention comprises two tubular coupling members l, 2, the outerends of which may be suitably shaped to receive hose sections, pipes orthe like.l As illustrated, said outer ends o' the members 1', 2 havehose sections Fi secured to them by clamps C, but; it will be understoodthat other condoctors may be attached to the members of the coupling andsecured in any suitable manner. The coupling member l consists of a bodysection 3 und :i detachable sleeve section 4, said sections preferablyhaving` :i screw threaded connection, :is shown at 5. The other member 2nlso consists of o body section 6 und a sleeve section or nnt whichlatter hos a screw threaded engagement with the former, as shown atti.'lhe body scction 6 of the member 2 is adapted to project through thebore or openinl S) in the sleeve section 4 of the member l und upon theinner end of said section l isl :i head 10 formed by an annular radiallyprojecting flange, which latter forms an annular shoulder. The flange orhead 10 is rranged in an enlarged portion l1 of the bore or open-Specifl cation of Letters Patent. Pa

as will be readily understood upon reference ce to Fig. 2 of thedrawings. The outei9 end." of the sleeve section l is-preferablyreduced.. .f to provide n cylindricol bearing hubflelff, which projectsinte :indV upon which iof tates a soelreted enlarged portion 15` on 'lo'one end of the'sleeve section or not 7' if." des1red,the\ex ter1or ofthe nut 7 nnen be. provided with lint faces 16 for the engugement of :iwrench or similar tool, whereby said nut may be rotated .for the purposeof com )Pessino the licking rin@ 13 and ro# t C C viding :in effectivefluid tight joint. The

sleeve section el may also `be providedwitb one or more lint faces forengogeu'lent. lifes wrench or similar tool and within said seo 8C tionbetween the Hooge. l() of the member 2 and the innert-nd ofthe section 3of 'the member l muy be provided-ii packing ringi i 13* as shown in Fig.2. f

In operation when it is desired to separate 8:5 the members, the nut 7is screwed inwardly to relieve the pressure on the packing i3, thesleeve section 4 is then unscrewed from the body section 3 of the member1, and when it is desired to remove the body section 6 9@ of the member2 from the sleeve section i of the other member, the nuo? is screwed o5of the section 6, whereupon, the latter may be slipped longitudinallycui of the section s.

From the fore-.goin it willbe seen that, the eculiar construction of thesevera-l portsY pro uces an exceeoingly effective swivel. coupling @hemembers of which may reedil. turn or rotate with res ect to each other,but'v at the same time ma e easily disconnected 10@ or detached. lt wilbe nrther'noted thatY the simple construction of the device provides :inexceedingly practical couplin which ma be produced si s small costnnolwhich wil be strong, durable in use, rind 105 which will provide uneii'eciive fluid tight joint.

Having thus described the inveniion what: is claimed is:

1. A detachable swivel hose couplin* com u() prising a mem r having atubular bo y section and a sl,eve section, the body section having anexternally screw threaded end, and the sleeve section havin a bore withan enlarged portion atl one en and a reduced bearing portion aty itsother end whereby an annular internal shoulder is formed between the'twoportions of the bore, the large por- 'tion of the bore having at its endinternal screw threads to receive the threads on the body' sectionwhereby the two Sections may be detaehably connected, the outer end ofsaid sleeve stion being formed with a reduced cylindrical bearingportion, a second tubular member arranged Within the sleeve section androtatable in the reduced portion of the bore of the same, the inner endot said second member bein formed with an annular radially projectmflange disposed in the large portion of t e bore of the sleeve section,the portion of said second member projecting beyond the outer end of thesleeve section being externally ,screw threaded, annular packing ringsarranged inthe sleeve member between'said flange and said internalshoulder and between said dan e and the inner end of the body section othe first mentioned member, and a nut engaged with the external screwthreads on the second member and having at its 4inner end a cylindricalsocket to receive and rotate upon the reduced bearing portion of thesleeve section of the rst mentioned member.

2. The herein described detachable swivel hose coupling comprising amember having body and sleeve sections, said body section l straight andtubular in shape and adapted to receive a hose section at one of itsends, its other end being externally screw threaded and' formed adjacent'thereto with portion at one end to provide an annular stop shoulder7said enlarged 4portion of the bore having its outer part i'nternallscrew threaded to receive the threaded ent of the body section, theexterior of said sleeve section being provided with fiatl faces, and itsother extremity being reduced to provide a cylindrical. bearing, asecond tubular ineinber having' a cylindrical end to rotate in the boreof the Sleeve section and formed with an annular radially 'projectingfiange arranged in the enlarged portion of the bore of said sleevesection, said Second tubular member having its other end reduced for thereception of a hose section and its intcrlne diate portion externallyscrew threaded, packin ringeI arranged in the enlarged portion o theslve section on opposite Sides of the fiange on the second tubularmember, and a sleeve nut having a dat faced exterior and internal screwthreads to engage the threads on the intermediate portion of the secondtubular member, said nut having its inner end enlarged and formed with acylindrical' socket to receive and rotate upon the reduced cylindricalbearing end of said sleeve section.
